Do you have a freestanding Amazon Fire box? I have a newish Samsung TV and didn't bother to activate the 'smart' features. I just use it as a monitor. The Fire (separate box) goes into an input on my A/V pre-pro and that connects to the TV. I think all you have to do is turn the volume on the TV to zero if you have a surround sound system hooked up to your receiver. (Unless you are talking about an audio only receiver, which may make things a little more complicated, but not impossible).
